The Redei-Berge Hopf algebra of digraphs
Vladimir Grujić, Tanja Stojadinović
In a series of recent talks Richard Stanley introduced a symmetric function associated to digraphs called the Redei-Berge symmetric function. This symmetric function enumerates des…
Fundamental groups of 3-dimensional small covers
Vladimir Grujić
Small covers arising from 3-dimensional simple polytopes are an interesting class of 3-manifolds. The fundamental group is a rigid invariant for wide classes of 3-manifolds, partic…
Weighted partitions enumerator
Marko Pešović, Tanja Stojadinović, Vladimir Grujić
To an extended permutohedron we associate the weighted integer points enumerator, whose principal specialization is the -polynomial. In the case of poset cones it refines Gessel…
Counting faces of nestohedra
Vladimir Grujić, Tanja Stojadinović
A new algebraic formula for the numbers of faces of nestohedra is obtained. The enumerator function of positive lattice points in interiors of maximal cones of the normal…
